Kelle & Jenn are at a pool. Kelle is standing on the high diving board while Jenn is standing on the low diving board. Assuming the difference in weight/mass is negligible, which of the following statements accurately describes this relationship? A. Kelle has a greater potential energy than Jenn.
B. Jenn & Kelle have equal potential energies.
C. Jenn has a greater potential energy than Kelle.
D. Kelle has a greater kinetic energy than Jenn.

A. Kelle has a greater potential energy than Jenn.

Explanation:

We need to apply the kinetic energy equation here to solve this problem: P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

The problem tells us, however, that mass/weight is negligible; therefore, the only thing that really matters here is the height. Kelle is higher up, so she would have a greater potential energy than Jenn, who is lower.

send me question so i can u
